Application Qctober 7, i940, Serial No. 360,059

'i claims. (01.-242-151) It is desirable in many instances that the first vfew turns of yarn on the yarn sleeve or tube be so wound that they may be easily pulled out from the completed package to form a tail which may be tied to the outer end of yarn on an adjacent package, when the yarn is being prepared for use in a subsequent operation.

It is the general object of our invention to provide an improved yarn and tail guide for uptwisters and similar machines.' which guide is adapted to guide the yarn in winding a tail at either end of a yarn package, and also to guide the yarn during the usual winding operation.

Our invention further relates to arrangements and combinations of parts whichwill be hereinafter described and more particularly pointed out in the appended claims. j

Preferred forms of our invention, as embodied in a winding machine of the up-twister type, are shown in the drawings. in which Fig. 1 is a partial front elevation of a portion of such a winding machine;

Fig'. 2 is a sectional side elevation of the mechanism shown in Fig. 1

Fig. 3 is an enlarged front elevation of one f form ofy our improved yarn and tail guide and Acertain associated parts;

Fig. 4 is a partial plan view, looking in the direction of the arrow 4 in Fig. 3;-

Fig. 5 is a partial longitudinal sectional view, taken along the line 5-5 in Fig. 3;

Figs. 6 and 'I are transverse sectional views, taken along the line 8`3 and 1-1 in'Fig. 3 respectively;

Fig. 8 is aside elevation of a modified conl struction of yarn and tail guide; and

Figs. 9, 10 and 11 aretransverse sectional views, taken along the lines 9 9, Ill-lli, and II-il respectively in Fig. 8. v

Referring particularly to Figs. 1 and 2, we have shown parts of a winding machine oi the uptwist" type, comprising a twister spindle I0 on which a supply spool S or other yarn package is mounted for rotation at constant speed. Ihe yarn Y is drawn upward from the spool S through a guide-eye I2, then over our improved yarn and tail guide G, and through a traverse guide I5 pivotally mounted rod I6.

The yarn Y is wound on a sleeve or tube T which is frictionally lheld on a roll 20, which in turn is pivotally mounted in the forked upper ends of a swinging supporting frame 22. The roll and the yarn thereon is yieldingly pressed against aA driving drum by a spring 26, and the drum .25 is constantly rotated by a driving shaft 21.

The tube T is preferably provided with a shalon a reciprocated traverse low groove in its outer surface and near one end of the tube, and the roll 20 is preferably provided with a V-shaped annular groove 32..,

' a substantially cylindrical body portion 40 hav-v ing slightly enlarged'end portions 4I and 42,A

'20 which in turn are provided with hooks 43 and 44,

Our invention relates particularly to the construction of the yarn and tail guide G shown in one form in Figs. 3 to 7. The guide G comprises all preferably formed integral in a single porcelain casting. The hooks 43 and 44 are spaced apart somewhat further than the length of thev regular yarn traverse.

The'guide G has a hole 45 extending axiallyy therethrough which loosely receives a supporting rod 50. The rod 50 isy secured by screws 5I in fixed frame members 52, which members also support upper and lower guide-rolls 53 and 54 forthe traverse bar i6.

The end portion 42 of the guide G is provided with an enlarged recess 55 (Fig. 5) and with a transverse opening 58. A collar 60 is loosely seated in the recess and is secured in position on the rod by a set screw 62 which extends out through the opening 58. The collar 60 and screw 62 thus constitute means for holding the' guide G on the rod 50 in any selected axial or angular position. The guide can be readily adjusted either axially ory angularly by simply into the V-shaped notch 32 in the roll 20 to se- 1 cure the 'yarn end, and the yarn is then placed under the hook or horn 43 on the guide G. As

lthe yarn is'drawn upward from the twister spindle by rotation of the roll 20, the hook 43 guides the yarn to the groove 30 which is near the end ,of the tube T and beyond the usual yarn traverse.

After a. desired number of turns have beenk wound in the groove I0, the yarn is .then manualwill be wound with the yarn guided by the hook M instead of by the hook 43 as shown in the drawings.

We have thus provided a single-piece porcelain guide. which is well adapted to guide the yarn during the usual winding operation and which is also adapted to guide the yarn when winding a tailon the tube, whether the spindle has a clockwise or an anti-clockwise direction of rotation. We have also provided extremely sim- Die means for adjusting the guide bothaxially and angularly on its supporting rod 50.

In Figs. 8 to 11 we have shown a modied construction in which a porcelain yarn guide 1|) is mounted on a rod 1| and is provided with hooks 12 and 13, all as previously described. The guide is, however, formed of U-shaped transverse section, as clearly shown in Fig. 10, and with a longitudinal slot 15 running lengthwise thereof and adapted to freely receive the rod 1|.

The guide 10 is provided with an end recess `16 to receive a collar 11, and is also provided with a transverse or radial opening 18 to loosely receive a binding screw 19 which engages the rod 1| and also projects outward into the opening 18. The collar 11 corresponds to the collar 80 (Fig. 5) previously described, and loosely positions the guide 10 both longitudinally and angularly on the rod 1|.

At its opposite end, the guide 1li is provided. with a recess B0 to receive a collar 8| having A from both collars, after which it may be removed radially from the rod 1|. Endwise removal or displacement of the rod 1| is thus unnecessary.

This modified construction possesses all of the uses and advantages previously described with reference to the construction shown in Figs. 3 to 7.

Having thus described our invention and the advantages thereof, we do not wish ltobe limited to the details herein disclosed, otherwise than as set forth in the claims, but what we 'claim is: 1. In a winding machine, a iixed supporting rod, a one-piece yarn and tail guide loosely mounted on and entirely supported by said rod, said guide having a portion with an axially elongated and substantially cylindrical yarn-guiding surface and having an integral tail-winding hook at each end of said body portion, and said guide being axially and angularly adjustable 0n said rod. and a single device effective to locate and secure said guide in both axially and angularly adjusted position on said rod.

2. In 'a winding machine, a supporting rod, a one-piece yarn and tail guide having a longitudinal passage therethrough to loosely receive said supporting rod and having an enlarged recess at one end of said passage and a communicating radial opening, a collar on said rod loosely fitting said recess, and a set-screw in said collar extending out through said radial opening and thereby positioning said yarn and tail guide both longitudinally and angularly on said rod.

3. A yarn and tail' guide for a winding machine comprising a tube having an elongated smooth body portion to guide the yarn during the regular winding of a yarn package and having a hook at one end of said tube adapted to guide the yarn in winding a tail at one end of said yarn package,

a positioning collar, said' tube being recessed at one end to receive said collar and having a radial opening communicating with said recess and coacting with a set-screw in said collar to axially and angularly position said collar and tube on a supporting structure.

4. In a winding machine, a supporting rod. a

one-piece combination yarn and tail guideV mounted on said rod and longitudinally slotted to freely receive said rod, means to position one end of said guide angularly and longitudinally on said rod and to prevent transverse displacement thereof, and means to prevent transverse displacement oi' the other end of said guide with respect to said rod.

`5. In a winding machine, a supporting rod, a one-piece combination yarn and tail guide mounted 'on said rod and longitudinally slotted to freely' receive said rod, said guide having a guide hook near one end and having enlarged axial recesses at both ends, collars on said rod loosely fitting said recesses and thereby preventing transverse displacement of said guide relative to said r'od, and means to secure said collars in adjusted positions on said rod.

6. The combination in a winding machine as set forth in claim 5, in which on'e of said collars is longitudinally slotted to receive said rod.

'1. The combination in a winding machine as set forth in claim 5, in which said ,guide has a transverse opening into one of said recesses and in which the associated collar has a clamping 4screw extending out into said transverse open-
